Stephen Hawking, in a recent lecture held at the Harvard University, claimed that black holes could be portals to a parallel universe. The celebrated physicist spoke at length about black holes and suggested that they neither store materials absorbed by them nor physical information about the object that created them.

Known as the information paradox, the theory goes against the scientific rule that information on a system belonging to a particular time can be used to understand its state at a different time. Over the years, it has been speculated that black holes do not retain information about the stars from which they are formed, except storing their electrical charge, angular momentum and mass.

According to Hawking, as per that theory, it was believed that identical black holes might be formed by an infinite quantity of matter configurations. However, quantum mechanics has signaled the opposite by revealing that black holes could only be formed by particles with explicit wavelengths. If the characteristics of the bodies that create black holes are not deprived, then they include a lot of information that is not revealed to the outside world, according to the physicist.

"For more than 200 years, we have believed in the science of determinism, that is that the laws of science determine the evolution of the universe" Stephen Hawking said. If information was lost in black holes, we wouldn't be able to predict the future because the black hole could emit any collection of particles."

In an earlier talk, Hawking had said things can escape out a black hole, both from the outside and probably through another universe. Currently, Hawking and his colleagues are working on understanding "supertranslations" to offer an explanation for the mechanism via which information is returned from a black hole and encoded on its event horizon.
